OpenAI has started ChatGPT Ads in over 60 countries, including Thailand. Ads appear as labelled "Sponsored" cards below the chatbot's answer, not inside it. Advertisers buy placement, not AI endorsement, and they bid on "Context Hints" describing the conversations where their product fits, not on search keywords. Advertisers see only aggregate impressions and clicks, not user chats. Ads are not shown to under-18s, on sensitive topics, or in Temporary Chat. For a small business, this is a new channel to test later, not an urgent switch away from Google or Facebook ads. Watch for the Thai rollout details and the Ads Manager setup before budgeting.
